Floor & balcony waterproofing in Riyadh: cost & published offers
In short: In Riyadh (Riyadh), floor & balcony waterproofing (cost & published offers) begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data). Published price: Bathroom waterproofing (per m²), SAR 15–40 per m²; anything else is quoted after the inspection.
Why floor & balcony waterproofing differs in Riyadh
Team note on Riyadh: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).

Riyadh's city centre sits about 637 m above sea level (SRTM open elevation data), a high inland plateau where the air is dry and the ground is often exposed to strong sun and sudden temperature swings. For floor and balcony work, that climate shapes what needs protecting. Heat makes surface coatings expand and contract, so the choice of material and the timing of application both matter for how long a finish holds up.
Because the plateau is dry, the main moisture threats are less about constant rain and more about occasional heavy downpours, water from rooftop tanks and bathrooms, and rising damp in basements. Our published rates reflect this mix. Basement waterproofing runs SAR 55–160 per m², bathroom waterproofing SAR 15–40 per m², and crack injection SAR 40–125 per metre, which is the first thing to consider when a hairline crack appears in a balcony slab. Liquid roof waterproofing is SAR 10–25 per m², bitumen membrane SAR 15–35 per m², and XPS boards SAR 15–30 per m², so owners can match the system to the exposed area rather than paying for a single heavy solution everywhere. Epoxy coating at SAR 35–95 per m², spray foam at SAR 20–45 per m², and tank internal coating at SAR 25–65 per m² cover the remaining surfaces, from wet floors to water storage.
Owners commonly avoid several costly errors by planning early. They do not seal a cracked surface without first injecting the crack, since the leak will simply reappear beside the patch. They do not treat a bathroom floor and a balcony with the same product when the wear and water exposure differ. They do not skip checking the drainage slope, because standing water undoes even a good membrane. They also avoid comparing quotes by the lowest per-metre figure alone, and they ask what preparation is included before work starts. Reviewing these points against the published ranges helps keep the final cost predictable.

How we choose the tool in Riyadh
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
The steps in order
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

Questions from Riyadh
What is the best thermal insulation material for a humid climate in the Eastern Province?
In humid areas, it is preferable to choose materials with low water absorption, such as extruded polystyrene or polyurethane foam, because they retain their efficiency in the presence of moisture. However, the final choice depends on the type of surface, the budget, and the contractor's recommendation after inspection.
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.
What is the first step of floor & balcony waterproofing (cost & published offers)?
We start with checking the falls (where water collects and where it should go), then details (thresholds, drains and upstands).
